In ResourceLoadStatisticsStore::hasStorageAccess() (ResourceLoadStatisticsStore.cpp:1678-1679), when ensureResourceStatisticsForRegistrableDomain() fails, the function returns without calling the completionHandler: auto result = ensureResourceStatisticsForRegistrableDomain(subFrameDomain, "hasStorageAccess"_s); if (!result.second) return; // BUG: completionHandler not called This causes the CompletionHandler<void(bool)> to be destroyed without being invoked. The IPC reply to WebProcess is never sent, so document.hasStorageAccess() JS Promise will never resolve.
